Specification of Letters Patent.

Patented May 25, 1915.

Application filed January 16, 1915. Serial No. 2,663.

To all whom it may concern Be it known that 1, Banner H. CAs'rLE, acitizen of the United States, residing at Quincy, in the county of Adamsand State of Illinois, have invented new and useful Improvements inHeating-Stoves, of which the following is a specification.

My present invention pertains to heating stoves; and it contemplates theprovision of a heating stove constructed with a View to assuring perfectcombustion of fuel, the utilization of practically all of the heat valueof the fuel, and the maintenance of a large body of air in close contactwith the heat to promote the thorough heating of the air in anapartment.

With the foregoing in mind the invention will be fully understood fromthe following description and claims when the same are read inconnection with the drawing, accompanying and forming part of thisspecification, in which the figure is a perspective view, partly insection and partly broken away, of a heating stove constructed inaccordance with my invention.

My novel stove is provided with the usual ash pit 1, fire pot 2, andcylindrical body portion 3, superimposed on the firepot and providedwith the conventional or any other suitable openings 4 and 5. At theupper en d of the fire pot- I prefer to employ a hollow annulus 6,communicating with the damper 5 and having a plurality of apertures 6designed to supply fresh air to the fire in the pot 2 with a view topromoting the combustion of the fuel. This annulus, however, is not ofthe essence of my invention and it may therefore be omitted withoutinvolving departure from my claimed invention.

At 8 the stove body is provided with an outlet for smoke and otherproducts of combustion, and it is also equipped with an interior hollowbaffle or deflector 9. This hollow bafi'le or deflector fits tightlyagainst the inner side of the body at opposite points, and is suitablyconnected to the body at the points 10 or at any other points compatiblewith the purpose of my invention. From a point below the outlet 8 to asuitable distance from the top of the body the hollow baffle ordeflector is arranged in spaced relation to the wall of the body, thisin order to afford a down flue 11 which constitutes an important part ofmy invention. Below the outlet 8 the battle or deflector 9 fits tightagainst the wall of the body around an opening 12 in said wall andthrough this opening the hollow baffle or deflector is connected with anexterior cold-air conduit 13. This conduit 13 extends downwardly to apoint at the underside of the ash pit 1 and is there preferably, thoughnot necessarily, provided with a contracted mouth 1%, designed toreceive air from a point adjacent to the floor of the apartment. At itsupper end the hollow baffle or deflector 9 merges into or is connectedwith an upwardly extending conduit 15 which extends through the top of1the stove body and is open at its upper enc.

In the practical use of my novel stove, it will be manifest that inpassing from the fire pot 2 to the outlet 8, the smoke, hot air andother products of combustion must first pass upwardly at one side of thehollow baflie or deflector, and then downwardly at the outer side of theupper portion of said baffle or deflector. From this it follows that theproducts of combustion are retained and circulated in the stove bodywith the result that the amount of heat radiated from the body ismaterially increased. It also follows that the conduct of the productsof combustion first upwardly and then downwardly in immediate contactwith the upper portion of the baffle or deflector as well as around andin immediate contact with the conduit 15 assures the thorough heating ofthe air that is carried upwardly through the conduit 13, the hollowbaffle or deflector and the conduit 15, with the result that theefficiency of the stove is materially increased. It will further benoted that when combined with the hollow foraminous annulus or gas ring6, the hollow baffle or deflector 9 assures perfeet combustion of all ofthe fuel before the same leaves the stove body, and consequently all ofthe heat value of the fuel is radiated from the stove body or else isutilized to heat the air that is conducted from the lower portion of theapartment through the baffle or deflector and back to the upper portionof the apartment.

Having described my invention, what I claim and desire to secure byLetters-Patcut, is:

1. In a stove, the combination of a body having an outlet for productsof combustion at an intermediate point in its height and also having anopening located below said outlet, an exterior cold-air conduitconnected with said opening and extending downwardly therefrom and openat its lower end,

a hollow baflle or deflector arranged in the body and having itsvertical sides fitting tightly against and connected to the inner sideof the body at opposite points and also having its lower portion fittedtight against the inner side of the body around the said openingthereof, and further having its upper portion spaced from the inner sideof the body from a point below said outlet of the body to the upper endof the baflle or deflector; the interior of said baffle ordeflectorbeing entirely isolated from the interior of the body, and a conduitcommunicatingwith the interior of the baflie or deflector and extendingthrough the top of the body and open at its upper end.

2. In a stove, the combination of a body having an outlet for productsof combustion at an intermediate point in its height and also having acold-air inlet arranged below said outlet, a hollow baffle or deflectorfixed in the body and communicating with said cold-air inlet and havingits interior entirely isolated from the interior of the body and alsohaving its upper portion arranged relatively to the wall of the body toform a down-flue that is closed at its sides and lower end and open atits upper end and leads to the outlet for products of combustion, and aconduit leading from the interior of the baffle or deflector through thewall of the body and open at its outer end.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
